I upset Alan Titchmarsh by growing everything in coir. I mix in
vermiculite for seed sowing. The main thing is getting the feeding
regime right as coir is both sterile and totally nutrient-free. I use
Westland multi-purpose or my own compost for larger stuff or JI No 2/3
with Perlite mixed in.

Virtual hydroponics then? The use of Rockwool etc proves that plants
thrive in any medium that incorporates air and moisture. Not my idea of
a flower bed mind :-)
